DESCRIPTION OF EMBODIMENTS

In the following an embodiment of the present invention will bedescribed.

1. Odor Adsorbent Material

As an odor adsorbent material, a resin, a paper, or the like may be usedby itself, or a laminated body thereof may be used. Furthermore, aresin, a paper, or the like by itself, or a laminated body thereof maybe used as a base material, and an odor adsorptive material such asactivated carbon and zeolite may be kneaded therein. Examples of theresin that can be used include polyethylene, polypropylene,polymethylpentene, polyvinyl chloride, polystyrene, polyamide,polyacetal, acrylic resins, polycarbonate, polyethylene terephthalate,polybutylene terephthalate, styrene based elastomers, olefin basedelastomers, vinyl chloride based elastomers, polyester based elastomers,polyurethane based elastomers, and nylon based elastomers.

In FIG. 1, (a) shows a plan view and a cross sectional view of oneexample of an odor adsorbent material 1 according to the presentembodiment. In this example, the odor adsorbent material 1 is a filmconsisting of polyethylene alone. The polyethylene film has highabsorption capacity against odor components, and odors in open space canbe easily transferred thereto. Thus, the polyethylene film can be usedas an adsorbent material for odor components.

In FIG. 1, (b) shows a plan view and a cross sectional view of anexample of another odor adsorbent material 1 according to the presentembodiment. In this example, the odor adsorbent material 1 is alaminated body obtained by laminating polyethylene films 3 on both sidesof an elastomer film 2. Alternatively, the elastomer film 2 alone may beused as the odor adsorbent material 1. Furthermore, other materials maybe used as the odor adsorbent material 1 as long as it is a materialthat has high odor adsorption capacity, maintains an adsorptive statefor a predetermined time period, and has less odor components in itselfsuch as a resin smell. The odor adsorbent material 1 preferably has anarea size not smaller than 100 cm2 for sufficiently adsorbing odorcomponents.

Odor components referred to overall substances having a bad odor or asweet smell, including mold odor components including haloanisoles suchas 2,4,6-trichloroanisole and 2,4,6-tribromoanisole, insect repellentssuch as naphthalene, agricultural chemicals or fragrances.

2. Odor Detection Kit

FIG. 2 is a plan view of an odor detection kit 11 according to thepresent embodiment. The odor detection kit 11 includes two pieces of theodor adsorbent material 1, a package section 12, and a sheet section 13.The package section 12 includes two storage sections 14 and 15, andpreferably has barrier property. Specifically, an oxygen transmissionrate of the package section 12 is, for example, 1 cc/m2/day or lower,and is preferably 0.1 cc/m2/day or lower. The oxygen transmission ratecan be measured using, for example, an oxygen transmittance measuringdevice manufactured by MOCON Inc., in accordance with a measuring methodindicated in each specification of ASTM D3985-81 and JIS K 7126B (equalpressure method). Furthermore, a moisture vapor transmission rate is 1g/m2/day or lower, and is preferably 0.1 g/m2/day or lower. The moisturevapor transmission rate can be measured using, for example, anmoisture-vapor transmittance measuring device manufactured by MOCONInc., in accordance with a measuring method indicated in eachspecification of ASTM F1249-90 and JIS K 7129B (infrared sensor method).Furthermore, if the package section 12 happens to have an odor, the odorwill be adsorbed by the odor adsorbent material 1. Thus, the packagesection 12 preferably has a low-odor property at a level so as nothamper an organoleptic test using the odor adsorbent material 1.

One example of the package section 12 is a pouch material. The pouchmaterial is formed by, for example, heat-sealing the margin of alaminated body including an aluminium layer. A fastener may be providedat the opening to enable resealing. Various materials can be used aslong as the advantageous effect of the present invention is obtained.One of the two pieces of the odor adsorbent material 1 is an exposureadsorbent material 16 that is to be exposed to open space to actuallyadsorb odors, and the other one of the two pieces is a comparisonadsorbent material 17 that is not exposed to open space. The exposureadsorbent material 16 and the comparison adsorbent material 17 arerespectively sealed and stored in the storage sections 14 and 15. Theexposure adsorbent material 16 and the comparison adsorbent material 17are preferably manufactured in the same batch and simultaneously storedin the package section 12. With this, the exposure adsorbent material 16and the comparison adsorbent material 17, at the time point when beingstored, are in a state of adsorbing the same substances at the samelevel, allowing a later described comparison to be performed easily. Aslong as the comparison can be performed, it is not necessary to have theexposure adsorbent material 16 and the comparison adsorbent material 17manufactured in the same batch and stored simultaneously. The odordetection kit refers to the odor adsorbent material 1, the packagesection 12, and the sheet section 13 before being assembled, and alsoafter being assembled.

The storage sections 14 and 15 may be two separate storage bags as shownin FIG. 2, or two storage sections formed in a single package section.Furthermore, the exposure adsorbent material 16 and the comparisonadsorbent material 17 may be stored together in either one of the twostorage sections 14 and 15.

The sheet section 13 includes an attachment area and an entry area. Tothe attachment area, the package section 12 and the exposure adsorbentmaterial 16 removed from the package section 12 are attached. For theattachment, the sheet section 13 may have a cut formed thereon, or apressure sensitive adhesive tape or the like that does not contain anodor component may be used. The sheet section 13 is made from, forexample, a paper, and the entry area is used for an entry using a pencilor an ink of a ball-point pen or the like not containing an odorcomponent such as a solvent. With this, it is possible to prevent anentry in the entry area using an ink that contains an odor component,causing the odor component to be adsorbed by the exposure adsorbentmaterial 16. As one example of the sheet section 13, a sheet materialhaving a rectangular shape with a height of 19 cm and a width of 26 cm,and a thickness of 5 mm or smaller may be used.

In the following, one example of the method for using the odor detectionkit 11 will be described.

The odor detection kit 11 is used at production facilities of acommodity and distribution facilities such as warehouses and containersfor transporting and storing a commodity, and is utilized for detectingodor when a quality problem has occurred. FIG. 3 is a flowchart fordescribing, as one example, one mode of installing, recovering, andtesting the odor detection kit 11 used in a container fortransportation.

3. Installation Method

In the following, a method for installing the odor detection kit 11according to one example will be described.

First, a commodity is transported in a container (step S101).

Next, the odor detection kit 11 is attached inside the container (stepS102). The odor detection kit 11 is attached by, for example, hooking ahole formed on the sheet section 13 on inner wall of a container door orthe like. In addition, the exposure adsorbent material 16 is taken outfrom the storage section 14, and the package section 12 and the exposureadsorbent material 16 are attached to the sheet section 13. At thismoment, the exposure adsorbent material 16 is attached on the uppermostsurface to be exposed to open space in the container. The comparisonadsorbent material 17 is not taken out from the storage section 15, andis attached to the sheet section 13 while being sealed and stored. Whenthe exposure adsorbent material 16 and the comparison adsorbent material17 are stored together in either one of the two storage sections 14 and15, the exposure adsorbent material 16 is taken out, and then thestorage section is sealed again while having the comparison adsorbentmaterial 17 stored therein.

Next, information specifying at least the time when the odor detectionkit 11 has been installed is entered in the sheet section 13 using apencil or an ink that does not contain an odor component (step S103). InFIG. 4, (a) shows a plan view of the odor detection kit 11 at thisstage. In the present embodiment, the name of a loaded object, the dateand time of loading, the name of a transportation company, and asignature of a confirmer are entered in the sheet section 13.

The odor detection kit 11 is transported together with the commodity(step S104).

4. Recovery Method

In the following, a method for recovering the odor detection kit 11according to one example will be described.

When the container arrives at a destination, the odor detection kit 11is removed (step S201). The exposure adsorbent material 16 is thenstored in the package section 12. At this moment, the exposure adsorbentmaterial 16 is stored and sealed in the storage section 14, not thestorage section 15 in which the comparison adsorbent material 17 isstored. By sealing in the exposure adsorbent material 16, volatilizationof odor components adsorbed by the exposure adsorbent material 16 isprevented. Furthermore, by separating the exposure adsorbent material 16from the comparison adsorbent material 17, transfer of odor componentsto the comparison adsorbent material 17 is prevented.

Next, information specifying at least the time when the odor detectionkit 11 has been recovered is entered in the sheet section 13 using apencil or an ink that does not contain an odor component (step S202). InFIG. 4, (b) shows a plan view of the odor detection kit 11 at thisstage. In the present embodiment, in the sheet section 13, the date andtime of shipment, the name of a transportation company, the presence ofan offensive smell in a sensory test, matters of special note, asignature of a confirmer, and an identification number of the containerare entered. It is preferable to enter, when recovering or installingthe odor detection kit 11, information that specifies a facility such asthe identification number of the container. With this, the container inwhich the odor detection kit 11 had been installed can be directlyspecified later.

Next, the whole odor detection kit 11 is sealed in a pouch materialhaving barrier property and low-odor property (step S203). As the pouchmaterial, for example, a sealing material having an aluminium layersimilar to the package section 12 can be used. With this, thepossibility of volatilization of an odor component adsorbed by theexposure adsorbent material 16 or the possibility of newly adsorption ofan odor component can be reduced with further certainty.

Next, the commodity is transported out of the container (step S204).

Next, the odor detection kit 11 is transported out while being sealedinside the pouch material. The odor detection kit 11 is transported to apredetermined storage location and stored (step S205).

An odor inside the container or the commodity may be performed when thecontainer arrives. When an odor is detected, transporting out thecommodity may be stopped. The testing method is not particularlylimited, and any predetermined method such as a physicochemical test oran organoleptic test may be executed. In the test, a part of one pieceof the exposure adsorbent material 16 may be used.

With the aforementioned installation method and recovery method, when anodor has been emitted in the container, the odor can be adsorbed by theexposure adsorbent material 16, and the exposure adsorbent material 16that has adsorbed the odor and the sheet section 13 having variousinformation regarding the facility and time of usage etc., can be storedand managed together for a long period of time. It should be noted thatthe order of steps S101 to S103 may be switched. Furthermore, as long asstep S203 is executed after steps S201 and S202, the order of steps S201to S204 may be switched.

5. Testing Method

In the following, a method for testing the odor detection kit 11according to one example will be described.

Generally, a commodity is given an identification number such amanufacturing number, and is distributed and provided to a user. Aproducer or a distributor manages an identification number inassociation with information that specifies each process in adistribution route. Thus, based on the identification number of thecommodity, it is possible to specify a facility used in each of theprocesses in the distribution route of the commodity, and the time whenthe facility has been used.

When a quality problem regarding an offensive smell on a commodity hasoccurred (YES at step S301), first, based on the identification numberof the commodity, the container that has transported the commodity andthe time of transportation are specified (step S302).

Next, based on information regarding the specified container and time ofthe transportation, and the content entered in the sheet section 13 ofthe stored odor detection kit 11, the odor detection kit 11 that hasbeen transported together with the commodity is specified (step S303).The content entered in the sheet section 13 of the odor detection kit 11is information that specifies the time of transportation and thecontainer to which the odor detection kit 11 has been attached, such asthe identification number of the container, the date and time ofloading, and the date and time of shipment.

By testing odor components adsorbed by the comparison adsorbent material17 and the exposure adsorbent material 16 of the specified odordetection kit 11, it is determined whether or not an odor had beenemitted in the container (step S304). The method for the odor test isnot particularly limited, and the odor test may be executed with anymethod such as a physicochemical test or an organoleptic test. A testresult of the comparison adsorbent material 17 is compared with a testresult of the exposure adsorbent material 16 in order to enhance thedetermination accuracy. Since the comparison adsorbent material 17 hadbeen under the same environment as the exposure adsorbent material 16except for being sealed also while the container has been transported,if more odor components are detected from the exposure adsorbentmaterial 16 than the comparison adsorbent material 17, the odorcomponents can be determined as being originated from the air within thecontainer with high accuracy. Furthermore, even when odor components aredetected from the exposure adsorbent material 16, if the detected odorcomponents are identical to those from the comparison adsorbent material17 in terms of the type of components and the amounts thereof, the odorcomponents can be determined as not being originated from the air withinthe container with high accuracy.

With the aforementioned usage method, it is possible to retrospectivelydetermine that an odor had been emitted in a facility in which the odordetection kit 11 had been installed, and rapidly determine whether ornot the facility is the cause when a quality problem has occurred. Theodor detection kit 11 can be installed, not only in a container fortransportation, but also in various facilities involved in each of theprocesses for the distribution of a commodity, such as each step in amanufacturing plant, a warehouse, and a cargo deck of a truck. When theodor detection kit 11 is installed in each of the facilities, it ispossible to rapidly specify a facility in which the odor had beenemitted.

6. [Modification 1]

In the aforementioned embodiment, a mode has been described in which theodor detection kit 11 is installed and recovered when a commodity istransported in and out. However, the odor detection kit 11 may beinstalled and recovered irrespective of the timing at which a commodityis transported in or out. For example, the odor detection kit 11 may beinstalled in a factory or a warehouse at any time, and may be recoveredafter a predetermined time period. Furthermore, the test for odorcomponents may be performed even when a quality problem has notoccurred.

It is possible to install, recover, and test the odor detection kit 11periodically for investigating whether or not an odor had been emittedin a facility such as a factory or a warehouse, and the time when theodor had been emitted. FIG. 5 shows a flowchart for describing one modeof installing, recovering, and testing in the above described case.

First, the odor detection kit 11 is attached inside a facility (stepS501). The present step is similar to the aforementioned step S102. Theexposure adsorbent material 16 is attached to the uppermost surface ofthe odor detection kit 11, and is exposed to open space in the facility.

Next, information specifying at least the time when the odor detectionkit 11 has been installed is entered in the sheet section 13 using apencil or an ink that does not contain an odor component (step S502).The present step is similar to the aforementioned step S103. In thepresent modification, in the sheet section 13, for example, the name offacility, the date and time of installation, and a signature of aconfirmer are entered.

After the predetermined time period has elapsed since installing theodor detection kit 11, the odor detection kit 11 is removed (step S601).The present step is similar to the aforementioned step S201. Theexposure adsorbent material 16 is sealed and stored in the packagesection 12 separately from the comparison adsorbent material 17.

Next, information specifying at least the time when the odor detectionkit 11 has been recovered is entered in the sheet section 13 using apencil or an ink that does not contain an odor component (step S602).The present step is similar to the aforementioned step S202. In thepresent modification, in the sheet section 13, for example, the date andtime of recovery and a signature of a confirmer are entered. It is alsopossible to perform the test of odor inside the facility when recoveringthe odor detection kit 11, and enter the result in the sheet section 13.

Next, the whole odor detection kit 11 is sealed in a pouch materialhaving barrier property and odorless property (step S603). The presentstep is similar to the aforementioned step S203.

Next, the odor detection kit 11 is transported to a test site whilebeing sealed in the pouch material, and the test is performed thereon(step S701). By testing odor components adsorbed by the comparisonadsorbent material 17 and the exposure adsorbent material 16 of the odordetection kit 11, it is determined whether or not an odor had beenemitted in the facility within the predetermined time period. Thedetermination method is similar to the method in the aforementioned stepS304.

In the present modification, emission of an odor in a facility withinthe predetermined time period can be investigated without constantlyplacing a person in the facility. The predetermined time period is aperiod of time determined discretionarily, and may be, for example, oneweek or one month. The time of odor emission can be specified moreprecisely when the predetermined time period from installation torecovery of the odor detection kit 11 is shortened. If the presentmodification is applied in, for example, a warehouse prior to storing acommodity, it becomes possible to determine whether a quality problemmay occur in the warehouse beforehand, and reduce the occurrence of aquality problem.

7. [Modification 2]

In the aforementioned embodiment, although an example in which the odordetection kit 11 includes two pieces of the odor adsorbent material 1has been described, the odor detection kit 11 may include, as amodification, a plurality of pieces of three pieces or more of the odoradsorbent material 1. In this case, the plurality of pieces of the odoradsorbent material 1 are used as the exposure adsorbent material 16, andthe plurality of pieces of the exposure adsorbent material 16 may beinstalled at multiple locations in the facility to enable improvement inprecision of odor detection. Furthermore, a plurality of pieces of theodor adsorbent material 1 may be used as the comparison adsorbentmaterial 17.

8. [Modification 3]

In the aforementioned embodiment, although the method for using the odordetection kit 11 has been described, the odor adsorbent material 1 maybe used by itself as a modification. That is, the odor adsorbentmaterial 1 is taken out from the package section and then attacheddirectly inside the facility as the exposure adsorbent material 16without being attached to the sheet section 13. Furthermore, the packagesection is not limited to the pouch material, as long as the packagesection has a certain level of barrier property and low-odor propertyand can prevent odors from being adsorbed by the odor adsorbent material1. For example, instead of the pouch material, the odor adsorbentmaterial 1 may be packaged in an aluminium foil. Furthermore, instead ofinstalling the comparison adsorbent material 17 in the facility, theodor adsorbent material 1 that has not been exposed may be stored in apredetermined location to be used as the comparison adsorbent material17. Still further, it is possible to not use the comparison adsorbentmaterial 17. For example, emission of an odor inside the facility can bedetermined by only comparing odor test results from an organoleptic testof the exposure adsorbent material 16 when being attached inside thefacility and after being recovered therefrom.

As described above, embodiments according to the present invention areuseful for odor tests etc., in facilities for producing and distributingcommodities such as food products.
